Possible grist for the classroom tax mill: Mike Tyson's tax problems, as reported by Sports Illustrated. Tyson received a $14 million payment from promoter Don King to settle his $100 million lawsuit, to be combined with purses from seven fights over the next three years as part of a bankruptcy reporganization plan, to pay off a $34.8 million IRS tax lien against Tyson and his ex-wife.
